6881699d76 Fix layering violation in isForeignWindow()
QPlatformWindow::isForeignWindow() should return whether
the native window is of the foreign window type, or
false if the platform (plugin) does not support this
concept.

It should not call QWindow::type(), since that function
may itself be implemented in terms of isForeignWindow().

a7cea16005 MSVC x86: implement add_overflow for quint64
There's no 64-bit ADD instruction, so we make do with ADD+ADC. This is
what Clang generates. ICC uses the two as well, but then performs some
subtractions to find out if it overflowed. GCC for some inexplicable
reason attempts to use SSE2 if that's enabled, otherwise it performs the
subtractions like ICC.

Alternative implementation which generates better code, but violates
strict aliasing:

 uint *low = reinterpret_cast<uint *>(r);
 uint *high = low + 1;
 return _addcarry_u32(_addcarry_u32(0, unsigned(v1), unsigned(v2), low),
                      v1 >> 32, v2 >> 32, high);

Manual testing shows this works. tst_qnumeric passes in debug mode. MSVC
2017 15.9 still miscompiles in release mode (reported to MS as [1]).

28b2232e78 Don't dither antialiasing on glyphs when converting to mono
When glyphs are converted to monochrome from an alpha map,
it does not make sense to apply high quality dithering, because
the result will be that some the subpixels along the edges
that cover only part of a pixel are filled. This causes the
glyphs to look jagged and ugly.

Instead, we use ThresholdDither to fill all pixels that are
>= 50% opacity.

e6880e7cd1 Fix text shifting vertically when elided
When eliding text we would check for the existence of the ellipsis
character and fall back to using the dot if it was not available.
However, when font merging was in use, we would also use ellipsis
from a fallback font if available. This could cause the metrics
of the text to increase if the fallback font had larger metrics,
and the result was that text could shift when elided.

It is better to prefer the dot from the current font than to use
the ellipsis from a fallback, so we only use the ellipsis if
it is in the main font.

[ChangeLog][QtGui][Text] Fixed a bug where eliding text could
change the height of its bounding rectangle for certain fonts.

this doesn't fix any actual bug, because mingw will apparently resolve

documented (on mingw.org). however, this mix of conventions is ugly and

65463764f2 configure: properly atomize xcb-syslibs
as it is now cheap to test for individual libraries and headers, split
the xcb_syslibs monster-library into its parts.
the compile test remains a single blob, though, as that didn't get any
cheaper. whether it's worth keeping it in the first place is debatable.

7a481fce28 configure: detect fxc.exe more thoroughly
When building ANGLE, we need the shader compiler (fxc.exe), which is not
shipped with MinGW. Previously, we required an installed DirectX SDK.
For Windows versions >= 8, the DX SDK is also part of the Windows Kit,
so we also allow the user to specify the location of the Windows Kit.
We also detect fxc on 64-bit hosts now, and in newer SDK versions which
version the binary directory.

The detected binary is now exported by configure, so the ANGLE project
file does not need to duplicate the logic anymore.

1ef9859e7e configure: refactor directx checks
properly atomize the libraries and express their dependencies, and
adjust the project files accordingly.

note that we don't try to use any additional paths, as all SDKs we
currently support have built-in directx 11 support:
- msvc2013 comes with win sdk 8.1; that is also used for win7 targets
- mingw-64 5.3 (though this one is missing fxc, which is why the code
  path for using an external sdk for that remains)

3ccdeb4b58 Remove specialized multi font engine on Windows
This was added as a platform-specific implementation of the multi engine
in 2005, before this code was generalized, and it currently only has the purpose
of special handling loadEngine().

The way this was special handled was by creating a new QFontEngine for every
fallback family *every* time, never checking if the font engine already exists
in the cache (like the superclass implementation does). The result of this was
that if you had 500 fonts and each of them had 500 fallback fonts, and made
a loop that would load all of them, then you would get 250000 font engines.
At some point before this, we would run out of available handles and crash.

There shouldn't be any need to have special handling of fallback font loading
on Windows (i.e. all the platform specific parts should go through the normal
mechanisms in QPA), so lets just go through the superclass implementation instead.

[ChangeLog][Windows][Text] Reduced the number of font engines that are
created when loading new fonts, fixing crashes in some special cases where
a large number of fonts are created during a short period of time.

Fixes: QTBUG-70032
